Libor scandal: Barclays was fined a record £290m in June for attempting to manipulate the London interbank offered rate (Libor), used to fix the cost of borrowing on mortgages, loans and derivatives worth more than $450m trillion globally. The fallout from Barclays’ involvement in the Libor scandal led to the departure of chief executive, Bob Diamond (pictured), and the chairman, Marcus Agius. More than a dozen major international financial institutions are now being investigated over their alleged attempts to rig Libor.Picture: Getty Images
